And first of laws concerning religion. We have already said that the number 5040 has many convenient divisions: and we took a twelfth part of this (420), which is itself divisible by twelve, for the number of the tribe. Every divisor is a gift of God, and corresponds to the months of the year and to the revolution of the universe. All cities have a number, but none is more fortunate than our own, which can be divided by all numbers up to 12, with the exception of 11, and even by 11, if two families are deducted. And now let us divide the state, assigning to each division some God or demigod, who shall have altars raised to them, and sacrifices offered twice a month; and assemblies shall be held in their honour, twelve for the tribes, and twelve for the city, corresponding to their divisions. The object of them will be first to promote religion, secondly to encourage friendship and intercourse between families; for families must be acquainted before they marry into one another, or great mistakes will occur. At these festivals there shall be innocent dances of young men and maidens, who may have the opportunity of seeing one another in modest undress. To the details of all this the masters of choruses and the guardians will attend, embodying in laws the results of their experience; and, after ten years, making the laws permanent, with the consent of the legislator, if he be alive, or, if he be not alive, of the guardians of the law, who shall perfect them and settle them once for all.
